Abstract Zn–Al–Mg coating galvanized steel in resistance spot welded (RSW) different configurations of DC51D was investigated to illustrate the nugget evolution process and mechanical properties joints. Results show that microstructure joints can be divided into zone (FZ), heat-affected (HAZ), base metal (BM). FZ composed lath martensite. The average hardness value weld joint 110 HV 0.2 while u...

Hot cracking susceptibility and the formation of brittle martensite phase are main factors that limit weldability a dissimilar joint between carbon steel (CS) austenitic stainless (SS). In this study, self-constraint finger test was used to correlate welding thermo-mechanical field with crack weld CS ASTM A36 SS AISI 304L. The allowed intercalate fingers (portions) tested materials in samples p...

The floating zone (FZ) method is one of the growth techniques used to grow single crystal materials. FZ growth is achieved in a containerless environment (without a crucible) by the movement of a molten zone of a solid rod, which forms a free-standing liquid bridge between two solid sections. However, the surface tension along the free surface of the molten zone varies due to temperature and co...

Field investigation, Microfacies analysis, and biostratigraphy have been carried out in the central parts of Ionian Basin (Aetoloakarnania area, Western Greece) order to decipher depositional environments that developed during accumulation Upper Cretaceous Eocene carbonate succession. Three different Standard types (SMF) observed, corresponding two (Facies Zones or FZ) a platform progradation. ...

In this study, the multi-objective optimization method for thin-wall milling of 6061 aluminum alloy is addressed. The technological parameters including cutting speed Vc, feed tooth fz, and width cut ar are considered input variables, while manufacturing responses surface roughness Ra, production rate MRR, flatness deviation FL. goal to find optimum minimize Ra FL maximize at same time. To solv...

Wnts are secreted cysteine-rich glycoproteins with diverse roles in animal development (reviewed in Cadigan and Nusse, 1997). Frizzled proteins are cell surface Wnt receptors characterized by an extracellular cysteine-rich domain (CRD) followed by seven transmembrane segments (Vinson et al., 1989; Wang et al., 1996). Members of both protein families have been conserved in species as evolutionar...

OBJECTIVE To provide the empirical basis for using ocular vestibular evoked myogenic potentials (oVEMPS) in response to Fz bone conducted vibration (BCV) stimulation to indicate vestibular function in human subjects. To show the generality of the response by testing a large number of unselected healthy subjects across a wide age range and the repeatability of the response within subjects. To pr...

Copper plays essential roles in biology, but abnormal interactions are damaging. Reliable quantification of copper-protein interactions will underpin the molecular understanding of copper nutrition and toxicity. We have previously established two high affinity probes, Bathocuproine disulfonate (Bcs) and Bicinchoninate (Bca) anions, that are capable of in vitro quantification of Cu(i) binding wi...

An analysis is given and proposals are presented to improve the maintenance level in implementation of law 297-FZ, Art. 11 by improving testability suitability for diagnostics resource-determining nodes domestic energy-saturated equipment

The regulation of firing thresholds of cortical pyramidal cells has been suggested as one of the mechanisms underlying the generation of the P300 component of the human event-related potential. According to this hypothesis, the detection of an important stimulus produces a widespread inhibition of "irrelevant" networks, interrupting the ongoing cortical activity and facilitating the analysis of...
